Hi there! I faced a lack of methods overloading in PHP once again and would like to ask will it be implemented at some point? As well, I want you to show some pros and cons which you see in this feature. Here're some thoughts about this by Yegor Bugayenko:
It looks like your message is missing at least a link. A quick search did however turn up a tweet where Yego suggests it's a code smell (which basically echos my thoughts below): https://twitter.com/yegor256/status/932701585339240449
A quick search shows the most recent discussion on method overloading here appears to be: https://externals.io/message/104073
The big problem with implementing method overloading in PHP is its typing system. It might be possible to implement it in certain cases where types are strictly defined for all parameters and return values, but I suspect there would still be issues over scalar types (particularly int/float) and union types.
My personal opinion is that method overloading is unnecessary, and can be detrimental to code readability when not used carefully. Without it I think developers are forced to name methods that do similar things more concisely, while when it's available they're more likely to create a "single" generically named, overloaded method whose behavior can differ depending on the inputs.
